FREE TOOL · DICOM / CBCT
Free online DICOM viewer.
Open dental DICOM series on your device: choose the series, navigate axial slices, linked MPR when geometry allows, adjust window/level, measure on a declared scale, and export an annotated capture. The study is not uploaded for viewing.
Pro v1: local review. Linked MPR and arch-MIP panorama when geometry allows. No automatic diagnosis, no HIPAA certification on this page.
Your CBCT will appear here.
Load a DICOM series or open the TL-DEMO maxillary demo to navigate slices, window/level, and measurements on a declared scale.

QUESTIONS ABOUT THIS VIEWER
The limit is part of the answer.
Is the dental DICOM viewer free?
Yes. Opening a ZIP or folder, reviewing slices (axial and MPR when geometry allows), window/level, and exporting PNG/JSON on this page have no charge. This page does not include diagnosis or the desk case viewer.
What DICOM files can this viewer open?
It opens native little-endian uncompressed DICOM, RLE Lossless, and JPEG Lossless (1.2.840.10008.1.2.4.57 / .70), single-channel 8/16-bit, including multi-frame extracted per slice and ZIP/folder in the browser. JPEG2000, JPEG Extended, and JPEG-LS are listed with the reason and are not rendered. That is not full DICOM conformance or a vendor matrix.
Can I view CBCT scans?
Yes, when the series is in the demonstrated subset (little-endian, RLE, or JPEG lossless). You navigate axial slices and, when ImagePosition/Orientation can build a volume, linked MPR (axial/coronal/sagittal) plus a labeled arch-MIP panorama. JPEG2000, JPEG Extended, and JPEG-LS are listed with the reason and are not rendered.
Are files uploaded to a server?
Not for viewing. Parse and render run in your browser. TrazaLab does not receive the DICOM content for this viewer. That reduces upload exposure; it is not a HIPAA certification and does not replace your organization’s controls.
What is window/level?
Window/level chooses which range of slice values appears as gray. This page includes dental (W 4000 / C 600), bone (W 2000 / C 350), soft tissue (W 400 / C 40), and the file values when they exist. The probe shows HU only with RescaleSlope and Intercept; otherwise it shows the raw value.
Does it offer MPR, panorama, or diagnosis?
Linked MPR (axial/coronal/sagittal) and an arch-MIP panorama when the series has enough geometry (ImagePositionPatient + ImageOrientationPatient). If it does not, the control stays disabled with the reason. The panorama is an orientation aid (MIP along a default arch), not a native OPG and not a diagnosis. It is not a diagnostic device or an implant planner.
How do millimetre measurements work?
When the active slice includes usable PixelSpacing, length uses row and column spacing (DICOM mm). If it is missing, the scale is marked unavailable: millimetres are not invented. The probe shows HU only with RescaleSlope and Intercept; otherwise it shows the raw value. Clinical interpretation stays with the professional.
What is the demo study?
TL-DEMO Maxila Axial is a synthetic non-PHI stack (maxillary axial arch) generated in the browser. It is for seeing navigation, window/level, and tools before you open your own files. It is not a real clinical case.
